Referring to FIGS. 3 to 6 , the lamp socket 315 may include a case 316 and a power transmission member 320 .

The case 316 accommodates the power transmission member 320 and may be inserted into the coupling hole 510 of the bottom frame 500 of FIG. 1 . To this end, the housing 316 may include a recess 317 that accommodates the power transfer member 320 .

The power transfer member 320 may include a conductive material and may be used to electrically connect the inverter 600 in FIG. 1 with the lamp 310 . The power transmission member 320 may include an inverter connector 321 , a first lamp electrode supporter 322 , a second lamp electrode supporter 323 and a terminal unit 340 .

The inverter connector 321 may extend toward the inverter 600 along the recess 317 . The inverter connection part 321 may have a multi-step structure corresponding to the structure of the recess 317, and a part of the inverter connection part 321 may be folded.

The second support part 329 may vertically extend from the first support part 328 and may form an insertion hole into which the lamp electrode 311 is inserted together with the insertion guide 325 .

The second lamp electrode supporter 323 may face the first lamp electrode supporter 322 such that the terminal unit 340 may be disposed between the first lamp electrode supporter 322 and the second lamp electrode supporter 323 as shown in FIG. 6 . Structurally, the second lamp electrode supporter 323 may be substantially the same as the first lamp electrode supporter 322 . Accordingly, similar to the first lamp electrode supporter 322 , the second lamp electrode supporter 323 may be formed with the lamp electrode receiving portion 324 . To avoid redundancy, a detailed description of the second lamp electrode supporter 323 will be omitted.

The terminal unit 340 may be formed in the case 316 , and a part of the terminal unit 340 may be bent several times in the case 316 . The terminal unit 340 elastically supports the lamp electrode 311 such that the lamp electrode 311 is attached to the fixing groove 326 . The first lamp electrode supporter 322 and the second lamp electrode supporter 323 can protect the terminal unit 340 , thereby protecting the terminal unit 340 from external shocks, and can reliably and conveniently assemble the terminal unit 340 .

The terminal unit 340 may have a contact pressure of about 1N (Newton) to about 5N (Newton) with respect to the lamp electrode 311 . If the contact pressure of the terminal unit 340 is less than 1N, the terminal unit 340 is not firmly attached to the lamp electrode 311, so that power is not reliably supplied. On the contrary, if the contact pressure of the terminal unit 340 is greater than 5N, a large amount of force is required to insert the lamp electrode 311, thereby reducing work efficiency.

The terminal unit 340 may include a fixed end 341 , a connection end 342 and a free end 343 .

The fixing end 341 may be fixed and may be located between the first lamp electrode supporter 322 and the second lamp electrode supporter 323 so as to connect the first lamp electrode supporter 322 to the second lamp electrode supporter 323 .

The connection end 342 may be connected to the fixed end 341, and may be bent in the case 316, thereby providing elastic force. The connection end 342 may not extend beyond the front ends of the first lamp electrode supporter 322 and the second lamp electrode supporter 323 . The first lamp electrode supporter 322 and the second lamp electrode supporter 323 may protect the connection end 342 .

For example, the connection end 342 may have a radius of curvature of approximately 0.3 mm to 1.0 mm.

The free end 343 may be connected to the connection end 342 and may be in contact with the lamp electrode 311 . The free end 343 may also be formed so as to protect the free end 343 from external impact. For example, the highest point H1 of the free end 343 may not be higher than the highest point H2 of the fixed end 341 . As shown in FIG. 5 , the highest point H1 of the free end 343 obtained in consideration of the horizontal movement of the free end 343 is located below the highest point H2 of the fixed end 341 .

The free end 343 supports the lamp electrode 311 and together with the lamp electrode receiving portion 324 fixes the lamp electrode 311 in place. The free end 343 may include a lamp clamping portion 344 formed at a region where the free end 343 contacts the lamp electrode 311 . For example, the lamp holding part 344 may be made in the form of a recess provided to oppose the fixing groove 326 of the lamp electrode receiving part 324 and surround a part of the lamp electrode 311 . The free end 343 can effectively support the lamp electrode 311 so that the lamp electrode 311 is attached to the fixing groove 326 .

The free end 343 may also include a spacing adjuster 345 connected to the lamp clamping portion 344 . The interval adjuster 345 may be formed by bending the tip of the free end 343 . In addition, the spacing adjustment member 345 may be located below the highest point H2 of the fixed end 341 to achieve structural stability.

When an external force is applied to the interval adjuster 345 , the interval adjuster 345 moves so that the interval between the free end 343 and the insertion guide 325 can be adjusted. For example, if the interval adjuster 345 moves leftward due to external force, the lamp clamping portion 344 of the free end 343 moves in a leftward direction accordingly. Therefore, the interval between the insertion guide 325 and the lamp holding portion 344 is enlarged, so that the lamp electrode 311 can be inserted into the lamp electrode accommodating portion 324 more easily, or the lamp electrode 311 and the lamp electrode can be accommodated more easily. Section 324 separates. Additionally, the use of spacing adjusters 345 can facilitate automated assembly work.

In the current exemplary embodiment of the present invention, the upper end of the lamp holder 315 may be located below the upper end of the lamp 310, so that the lamp holder 315 may be used for a thin display device.

In step S21, the free end of the terminal unit is moved by moving the interval adjuster of the terminal unit, so that the interval between the free end and the lamp electrode accommodating portion into which the lamp electrode is inserted can be enlarged. in the interval between. The interval adjuster of the terminal unit may be moved using the first jig of the assembling device. At this time, the space adjusting member can be moved toward the fixed end, so that the free end moves away from the lamp electrode accommodating part. Afterwards, the space adjuster may be held fixed using the first jig, thereby maintaining the enlarged space between the free end and the lamp electrode accommodating portion.

In step S31, the lamp electrode is inserted into the lamp electrode receiving part, and the power transmission member is attached to the lamp electrode. The second jig of the assembly device can pick up the lamp so that the lamp electrode can approach the lamp electrode receiving portion.
